jpgolicacn filed. November 2, 1915.

To all whom t may concern Be it known that we, lRAs'iUs Dniiliieii aiiillinrvni' l?. Mnniis. citizens of the United Staies, residing; at Liilile Rock, in the county of .Pulaski and State oi Arkansas, have invented new and useful Improvements in Faint-Sp 'a5/s7 of which the following is a specification.

Our invention relates lo ii'iiprovcnients in paint sprays, or devices for applying liquid coating coii'ipositions.

Our object is to provide a machine of this character which will be thoroughly "practical. inoXpciisii/'c ol iiiaiiii'ictiire by reason oil its very simplc coiisifriiciiion and .vhicii will alaiii the. higlies .'i'egrec ol' eliicienin/ possible in devices designed lo do away with the tcflious process oli applying pain! :imi like. substances by nicans` of brushes.

Tho several advantages of our invention will be licreiniifvr explained and the. fein ini-es o construclion ilcscribed. in detail, i" i4" cronccbein'h' hail to 'clic drawings ivliii forni a part of this application.

cock lll by which thc painter may cont-rol the flou' through the spray-nozzle.

ln perfecting' ay thoroughly practical paint spray ive have found that it, is essential to provide an adequate and comparatively' air tight closure for the paint tank or receptacle for the purposc of excluding any foreign substance therefrom and to prevent waste and deterioration of the paint diie to evaporation and exposure to the atmosphere. At the saine time it is necessary to allow for admission of air to the tank as the paint thais in. is consumed. Consequently We have provided ibs inlei'l air-valve l.

The operation of the device is as follows:

Paint having bcon poured into 'the tank l hrougli the openingthe clieeli valve i2 in air @not 9, which duct is connected Willi a source of suppljii of coinpressefi air not in in the raivings, is opened., allowing; f to fiow--at a minimum pressure of -ilirough the air nozzle l0 andv agli pipes 8 and 13 out through the @lo iii, Then the check valve 6 in ic ii pi, e fi opened which allows the paint to ilosoenil through said pipe.. The rapicl rush oi"- conipressecl air from 'nozzle 10 creates a vacuum behind the delivery en of tlio nozzle, sucking the painlinto' anni i-.lirougli the pipes 8 and 13 to the spray-iiozzle. from which il; issues in a fine evenly divided spray; .K

YWhen lhs painter desires foiany purpose 'to shin"v oli' the flow of paini; lo the ,sprayv` nozzle he closes the cock l@ Snel; closure causes the flow of iii-until check valve l2 be turned-to pass up `rough pipe 5 into the, paint container. li; is therefore necessariY lo have a suitable outlet for such excess air and lio this end We have provicle the outlet airvalve 3 above referred to. The passage oi compressed air up through the paint in the tanl: serves to agitate and thorH oiigiglily inizi the saine and thus rcnrcz's iinnocessary any stirring to keep the liquiL in flic reqnirc. oonilition, to mingle readiljvr and evenly with thc air as passes through l'lii pipes and spray-nozzle.

The cover la for the tank provides cas access tlici'oo for the purpose otr' cleanin on tin i,

anil ilie pipes and paris of the coupling anl air-nozzle nni'v bc readily disengaged 'for a. like purpose. which is, oi course' very in1- portarli: in ordinto remove such jpainJ as afheres to the insides of the tank, pipes, an Coupling, before it dries ont.

Having described th'e features und udventages of our iiivention,wlmt we elimini as iiovelend desire to secure by Letters Patent, is:

A device of the character described, comprising a substantially air tight and dust proof liquid container, a closure therefor, n feed pipe leading therefrom, :i compressed air supply duct, a coupling connecting said feed pipe and said duct, an 'outlet pipe lending from said coupling, :L cut-off means in said outlet pipe, and automatic air .inlet und air outlet valves for said container communicating with the interior of the contaiiier and the outside atmosphere, seid outvlet valve eoper-fiiiiig with Huid eut-oli' iiicaiib und compressed nir supply duet to provide for egitutionoi the mixture within the container by seid Compressed air, and said inlet valve serving to eupply the necessary air to the interior of seid container to prevent the formation of' u vacuum therein and consequent stoppage o i the How of the mixture through Sziid l'eeflpipe.
